Prince Harry says his late mother Princess Diana is his "ideal role model" and has praised her for "putting her name towards some of the big issues" that hadn't been addressed before.

The flame-haired royal has praised his late mom - who passed away in August 1997 after a car accident - for "putting her name towards some of the big issues" that hadn't been addressed before.

Speaking at a summit in Chicago held by former US President Barack Obama, he said: "I think she had a lot in common with everybody, but she would also listen. She put her name and platform towards some of the big issues which had never been talked about before. We suffer from this illusion, or reality I suppose, where some problems become so big no one wants to get involved. She was the one who wanted to change that. I will always look up to her as my ideal role model. Everything she did was having an impact, it was making a difference."

Prince Harry has been keen to follow in his mother's footsteps and recently gave a speech when he encouraged young people to "look up from their phones" and go out and "change the world".

He said: "The thousands of you gathered here are proof that today's generation of young people is the most connected, most energised, and most confident the planet has ever known. You know that differences of opinion, of circumstance, of race and religion - are to be respected and celebrated.

"You know that in a clickbait culture, we cannot waste time sharing and drawing attention to things that make us angry, or that we know to be false. You all know that it's great to 'like' things on social media, but that it's more important to look up from our phones, to get out into our communities, and to take real action; to stand up for what you believe in."
